我正在运行一个简单的测试，其中KieSession在STREAM模式下运行。我将“MyEvent”定义为一个事件，并指定它应该以3s到期。插入事件后，我处理KieSession，休眠5秒（允许计时器到期），然后尝试重新加载会话。但是，当我尝试重新加载会话时，我得到的异常类似于下面显示的异常。
提前感谢任何见解。

答案 0 :(得分：0)
我们有一个以STREAM模式运行的会话已被处理（！），然后再次从帽子中取出。我认为已经处置的会议已经消失，死亡和埋葬：所有资源都已被放弃。
另外，我想知道你打算用触发一个带有fireAllRules的实时时钟运行的事件处理会话，这个会话首先不允许超时到期。 fireUntilHalt将用于事件处理。
此外，将待处理的超时“置于冰上”引起了对Drools应用程序逻辑一致性的严重怀疑。如果计时器在会话休眠期间到期，则应撤回事实和/或触发规则，这应触发其他事实，依此类推。通常情况下，此类行为取决于“按时”或“及时”完成，而非冰解冻时。
